mini maglight waterproofing

river rock · Oct 10, 2010

not sure how deep this will work but i found if you fill and lube all the o-rings in a mini mag light you can use it under water i have only tried it in a cup for now but i will be going bigger i am useing 100% pure petroleum it works very well and once i find out more of how deep it can go i will update

Any other things that work please post

Overtime, petroleum will degrade silicon o-rings. You may want to check out the Comprehensive Grease and Lube Thread for a better long-term alternative. I have been happy with Nyogel 760G on my lights.

Maglite themselves (used to?) advise using petroleum jelly on their lights. I don't know what they use for the o-rings, however.

For what it's worth . . . .

I once read of a fellow who subjected a standard Mini-Mag flashlight
to a depth of 200 feet, and it worked fine. Suffered no ill-effects.

Note Well -- he did NOT activate the switch (twisty) while underwater !

Ahh, yes . . . .

But you are not at a Depth of 200 Feet !

That makes quite a bit o' difference.

I dunno. Given a well-sealed inductor and stuff, the mag light could be flooded without (immediate) ill effects. There's not much high-voltage going on, and water's not THAT conductive.

The real, "acid test" would be . . . .

Has any water gotten inside ?

Not simply: "does the light still Work" ?

BTW, i read that account many years ago, so it was the old, classic "hot-wire" mini-mag.

Certainly sounds like something FUN to test, eh ? ? ?
